Mine was perfect, I had a problem with the output and sent it to Audio Aero directly (I am in Europe). They delivered the player perfectly repaired in few days (a week or so).
I have a 3 year old AA Capitole MKII with the 6.4 chip in it. I am the second owner. The player has about 2000 hours on it with no problems so far. I had the SE upgrade on the output board done this year by Globe Audio and it's still going. Sorry to hear about your experience but I sent a few emails to Audio Aero when I got this player asking for a manual for it and I also got no replies, maybe I should have tried typing them in french.
My own experience with all of the Audio Aero people has been excellent. I got a Mark II with one of the first P4 chips and it had some 'ghosts' in it and the folks at Globe were very helpful even though I am the second owner.
My experience with repairs has been with Darryl at Digital Systems in Texas. Darryl is a gentleman and asuming he has the parts he usually has the unit back to you in about ten days. He also upgraded the power supply in my Capitole amp and his fees are reasonable.
